This paper studies the age and the growth of male and female of the Tunisian blue mackerel Scomber scombrus during 2004–2006. The age was determined by interpreting and counting daily increments on the otoliths sagitta of 320 individuals sampled from landings caught by different gears specially by purse seine. The parameters of the Von Bertalanffy growth curve were estimated for sexes combined: Lf = 31.46(1 − e−0.228 (t+3.034)) (L∞ = 31.46 cm, k = 0.228 per year, t0 = −3.034 years); for male Lf = 27.43(1 − e−0.422 (t+1.747)) (L∞ = 27.43 cm, k = 0.422 per year, t0 = −1.747 years) and for female Lf = 31.70(1 − e−0.227 (t+2.196)) (L∞ = 31.70 cm, k = 0.227 per year, t0 = −2.916 years) for the whole study period. The difference between the growth of male and female is not significant. The relationship between length and weight shows a length growth faster than of the weight with parameters of the equation Wt = a*Lb; a = 9.89*10−5 and b = 2.37 for the sexes combined.

Objectives To examine the relationship between height gain across childhood and adolescence with knee osteoarthritis in the MRC National Survey of Health and Development (NSHD). Methods Data are from 3035 male and female participants of the NSHD. Height was measured at ages 2, 4, 6, 7, 11 and 15 years, and self-reported at ages 20 and 26 years. Associations between (i) height at each age (ii) height gain during specific life periods (iii) Super-Imposition by Translation And Rotation (SITAR) growth curve variables of height size, tempo and velocity, and knee osteoarthritis at 53 years were tested. Results In sex-adjusted models, taller height at 4 and 6 years were modestly associated with decreased odds of knee osteoarthritis at age 53 (ORs per 1cm increase in height at age 6: 0.97 and age 4: 0.98 (95% CI: 0.95-1.00)). These associations were attenuated after adjustment for potential confounders. Similarly, taller adult achieved height measured at 26 and 53 years of age were associated with decreased odds of knee osteoarthritis (OR per 1cm increase in height: 0.98 (95% CI 0.96 to 1.00)). No associations were found between height gain during specific life periods or the SITAR growth curve variables and odds of knee osteoarthritis. Conclusions There was some limited evidence to suggest that taller height in childhood is associated with decreased odds of knee osteoarthritis at age 53 years in this cohort. This work enhances our understanding of osteoarthritis predisposition and the contribution of life course height to this.

Chapter 3 discusses Deucalion and Pyrrha’s regeneration of the human race after the destruction of the flood. The chapter links the hermeneutic ‘transformation’ of stones to bones both to a thematic interest within the narrative in the relationship of the new future to its Iron Age past, and to the readers’ experience of the text before them. The key to perceiving the connections between the content and the real-world presence of Ovid’s text is the phenomenon of sexual difference. Within the narrative, the opposition between male and female encodes the difference between an ordered, stable future and a rebellious past. But this tension also involves the relationship between the new forms imposed on the world and the subsistence of a material stratum that implies sameness. New transformations, like Deucalion’s of bones to stones, struggle to reconfigure reality, while the readings of a Pyrrha threaten to erase this difference. The chapter suggests that Ovid’s foregrounding of gender as a formal aspect of his text helps to create a parallelism between the experience of the reader and the hermeneutic challenges that play out within the story.

This study explored the relationship between sex-role development and response to taking medication by male and female psychiatric inpatients. The major hypotheses were that the more feminine an S's orientation the less resistance he would show to taking medication, the fewer adverse side effects he would report, and the fewer unusual body distortions he would acknowledge. All hypotheses were supported for women, and trends were noted for the second and third hypotheses for men. Differences between the men and women in length of hospitalization and drug treatment may account for the difference in results.

A custom in-the-ear (ITE) hearing aid fitting was compared to two over-the-ear (OTE) hearing aid fittings for each of 9 subjects with mild to moderately severe hearing losses. Speech intelligibility via the three instruments was compared using the Speech Intelligibility Rating (SIR) test. The relationship between functional gain and coupler gain was compared for the ITE and the higher rated OTE instruments. The difference in input received at the microphone locations of the two types of hearing aids was measured for 10 different subjects and compared to the functional gain data. It was concluded that (a) for persons with mild to moderately severe hearing losses, appropriately adjusted custom ITE fittings typically yield speech intelligibility that is equal to the better OTE fitting identified in a comparative evaluation; and (b) gain prescriptions for ITE hearing aids should be adjusted to account for the high-frequency emphasis associated with in-the-concha microphone placement.

Summary: Our meta-analysis focused on the relationship between homocysteine (Hcy) level and the incidence of aneurysms and looked at the relationship between smoking, hypertension and aneurysms. A systematic literature search of Pubmed, Web of Science, and Embase databases (up to March 31, 2020) resulted in the identification of 19 studies, including 2,629 aneurysm patients and 6,497 healthy participants. Combined analysis of the included studies showed that number of smoking, hypertension and hyperhomocysteinemia (HHcy) in aneurysm patients was higher than that in the control groups, and the total plasma Hcy level in aneurysm patients was also higher. These findings suggest that smoking, hypertension and HHcy may be risk factors for the development and progression of aneurysms. Although the heterogeneity of meta-analysis was significant, it was found that the heterogeneity might come from the difference between race and disease species through subgroup analysis. Large-scale randomized controlled studies of single species and single disease species are needed in the future to supplement the accuracy of the results.
